Active tuned vibration absorber

An active tuned vibration absorber 100 for reducing vibrations in a structure is provided. The active tuned vibration absorber 100 is housed in a housing 200 that has a cap 210 for connecting the active tuned vibration absorber 100 to an electrical power source. The cap 210 comprises one or more electrical power inputs 220 and one or more electrical connectors 230 for coupling the respective one or more electrical power inputs 220 to the active tuned vibration absorber 100. Each of the one or more electrical connectors 230 comprises an elongate pin (310, figure 3a) protruding from a substrate and surrounded by an electrically conducting coiled spring (320, Figure 3a) electrically connected to the elongate pin. The coiled spring has a first portion (340, figure 3a) proximal the substrate having a first uncompressed length and a first radius about a longitudinal axis of the elongate pin, and a second portion (350, Figure 3a) distal the substrate for contacting a respective contact pad coupled to the active tuned vibration absorber 100. The second portion has a second uncompressed length, and a radius that flares radially outwardly along its second uncompressed length from the longitudinal axis of the elongate pin.
